COP-SKEWER.

SPECIFICATION forming part of Letters Patent No. 762,018, dated June '7, 1904.

Application filed January 4:, 19%.

To all whom, it may concern:

Be it known that I, ARTHUR IV. BEARDSELL. a citizen of the United States, and a resident of Milford, county of Worcester, State of Massachusett's, have invented an Improvement in Cop-Skewers, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

In the use of cop-skewers in loom-shuttles it has been found that the sudden stoppage of the shuttle at the end of its shot when traveling in the direction of the point of the skewer tends to move the cop forward toward the skewer-point. This is due to the fact that the momentum of the cop tends to slide the cop-tube forward when the shuttle is suddenly stopped, notwithstanding the expansive force exerted by the split blade of the copskewer. The forward movement of the cop displaces it, and at times causes it to either become loose on the skewer-blade or the nose of the cop will be pushed off, causing the yarn to snarl and break. In looms provided with automatic filling-replenishing mechanism a fresh filling-supply will then be inserted in the shuttle and the ejected cop will contribute largely to waste.

My present invention has for its object the prod notion of a removable cop-skewer adapted for use in connection with shuttles used in automatic filling-replenishing looms, and it is constructed and arranged to prevent any forward movement of the cop on the skewerblade, whereby the objections specified willbe obviated.

Figure 1 is a view in side elevation of a copskewer embodying one form of my invention and arranged for use in an automatic fillingreplenishing loom; and Fig. 2 is a longitudinal sectional view of the head of the cop-skewer, showing the connection between it and the blade whereby the disarrangement of the cop is prevented.

In accordance with my present invention the blade is so connected with the head as to be capable of a slight longitudinal movement relatively thereto in the direction of the tip Serial No. 187,625. (No model.)

being made quite thick and having a central opening 5 and an annular concentric recess 6 in its inner face. (See Fig. 2.) The skewerblade 7 split longitudinally and sprung outward, as at 8, in well-known manner, is reduced in diameter at its butt 9 to'slidingly fit the hole 5 and having an annular shoulder 10, which bears against the outer face of the end 4 of the bushing. A metallic washer 11 is placed on the reduced end 12 of the butt 9, and

the outer end of such reduced portion is upset or headed over, as at 13, to securely hold the washer in place, said washer being slidably supported in the open end of the bushing 3. The inner face of the washer has an annular socket 14:, and a spring 15 is coiled around the butt 9 and seated at its ends in the sockets 14 and 6 of the washer and bushing end, respectively, the spring by its expansion causing the shoulder 10 of the blade to seat on the bushing end, as shown in Fig. 2. When the shuttle is traveling in the direction of the point of the skewerthat is, from left to right, viewing the drawings-the momentum of the cop acts to move the blade forward in the direction of arrow 20, Fig. 2, when the shuttle is stopped in the box. This movement of cop and skewer-blade is cushioned and gradually overcome by the compression of the spring 15, and immediately the spring expands and returns the blade to its normal position with relation to the head 1. As the blade can move with the cop thereon, the tendency of the cop to slip forward on the blade is overcome, and the momentum is gradually taken up by the compression of the spring.

It will be understood by those skilledin the art that the head of the skewer being held in the jaws mounted on the shuttle must move with the shuttle and also stop therewith as if an integral part thereof, while the connection between the head and blade of the skewer permits relative movement of such parts, shock being obviated by the use of the spring.

Having fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

A cop-skewer for automatic filling-replenishing looms comprising a tubular head having annular projections adapted to be detachably engaged by holdingjaws in a shuttle, a bushing fixedly secured Within the head and having an axial opening in its inner end, a blade having its butt reduced to slide longitudinally in said opening, a washer fast on the outer end of the butt and slidable in the bushing, a spring interposed between said washer and the inner end of the bushing, and a stopshoulder on the blade to cooperate with said bushing end.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ARTHUR W. BEARDSELL.
